Fig. 4: Relationship between leaf NSC and water status, and distributions of species-level seasonal shifts in leaf NSC allocation.
From: Non-structural carbohydrates mediate seasonal water stress across Amazon forests
Relationship between a leaf SS:NSCT (proportion of leaf NSCT in the form of soluble sugars) and midday leaf water potential (ΨMD); c leaf starch and ΨMD. Distributions of species-level seasonal shifts in b leaf SS:NSCT allocation (SS:NSCT Wet − SS:NSCT Dry) and d starch allocation (starch wet − starch dry). In the panel a and c the SS:NSCT, starch and ΨMD represent mean of all species sampled in each site in the dry season, except in the two sites where there is no dry season (monthly precipitation ≤ 100 mm month−1). Vertical and horizontal bars denote one standard error of the mean. The relationship between SS:NSCT, starch and ΨMD was fitted using standardised major axis (SMA) regression. In the panel b and d sites are ordered from top to bottom from drier to wettest. Long vertical black line denotate the mean ΔSS:NSCT and starch, each dot represents one species. Values to the left of the blue line denote species that increased SS:NSCT and starch in the dry season while those to the right of the line increased SS:NSCT and starch in the wet season.
